I don't remember a sweater like that. Back then we were all into tee shirts, bell bottoms, and bold geometric patterns. My favorite jeans were blue bell bottom jeans with white stripes and big red stars all over. You were a geek if the bottom of your jeans didn't drag on the ground. The wider the bell, the cooler you were. Now picture bell bottoms dragging on the ground while wearing 8 inch platform shoes. It was quite a trick. A sweater like that would have been too conservative (establishment) for us hippies. Gee, I'm telling my age.
